Mitigation checklist
- To mitigate this issue, restrict network access to the Keycloak Admin REST API to only trusted networks or localhost. This limits the attack surface by preventing unauthorized access to the API endpoints required for exploitation. Consult your network security documentation for specific firewall or network access control configurations. This may impact remote administration capabilities.
